2018 Ford F-150: shudder or vibration when accelerating

Filed Aug 13, 2026 · Transmission · OH

Transmission shudders until it gets warm, then it slips when accelerating after it's warmed up. Sometimes it goes completely out of gear. I've had the recall update done on the TCM and it made it worse. It has been confirmed by a service center. There are no messages or warning lights and it started slipping 6-8 months ago and has gotten worse. I cannot drive it currently.

On XXX at approximately 5pm my passenger and I were traveling west on the XXX from [XXX] to [XXX]. While driving at highway speeds with cruise control on at approximately 75/80 miles an hour, my 2018 F150 3.5ecoboost with the 10R80 10-speed automatic transmission suddenly without any input from myself, the transmission jerked out of gear causing the rear end to shudder violently. The vehicle briefly went into limp mode, after I pulled over and stopped, I turned the vehicle off and let it sit. When I turned it back on the limp mode went away but the transmission felt like it was slipping gears. My vehicle has only had light city and highway driving and never towed anything. With the known issues and on going class action lawsuits against Ford Motor Company regarding the 10R80 transmission, evidence shows my vehicle is also suffering from the known dangerous 10R80 10-speed transmission issues.

My 2018 Ford F‑150 experiences harsh shifting, sudden downshifting, gear hunting, delayed engagement, and shuddering during normal operation. These issues occur regardless of weather, temperature, or driving conditions and present a serious safety concern when accelerating or maintaining speed. Detailed Description of the Problem: The transmission consistently behaves unpredictably, including: Abrupt and harsh upshifts Sudden, unexpected downshifts (including multi‑gear drops) Gear hunting at steady speeds Shuddering or vibration during light acceleration Delayed engagement when shifting from Park or Reverse These symptoms occur every time the vehicle is driven, whether accelerating from a stop or maintaining a constant speed. The behavior is unpredictable and creates a risk of loss of control, especially when merging, crossing intersections, or driving in traffic.

Vehicle shifts hard and sometimes goes to high RPM before it finds a gear. It also slams into gear once it finally does go into gear. It also shudders when downshifting to pass and feels like the truck is about to fall apart while shaking

[XXX] Noticed hard shifting while ascending a 13% grade at [XXX] , while ascending for a brief period I lost forward power, throttle was unresponsive. I noted the shift dashboard fluctuating between various gears as though confused as to which gear it should be in. [XXX] Hard shifting between 3rd-4th and 3rd-5th becoming more consistent and noticeable. [XXX] I've been driving this vehicle a lot less but today while driving to my storage room with items loaded in my bed (should be noted, the items were not a weight concern) on the 10 freeway west bound at highway speeds, the truck throttle became unresponsive and once again, seemed to fluctuate between 1st and 10th gear. I found myself in between several big rigs, I was in the #1 lane passing a semi to my right, in between 2 more semi's one in front, one to my rear. The truck slowed down on the freeway, throttle became unresponsive. For that moment, my drivetrain was completely unresponsive. Roughly 20-30 seconds later the transmission decided to land in 7th gear with a loud "thunk" noise accompanying a sudden shudder in the vehicle as I applied the throttle to resume highway speeds. Although at that point, I was very tender with the truck, for the rest of the trip I experienced no further issues other than the 3-5 hard shift. On or about [XXX], I moved the truck from the old house to my new house, approximately 30 miles away. For most of the trip the transmission only exhibited the 3-5 hard shift but at the last mile or two, the drivetrain, became completely unresponsive for more than a minute, shifting between multiple gears, at one point, locking up briefly before resuming. Fortunately I was only driving around 30mph and in a residential neighborhood. At this point, I'm afraid to drive it. I've made an appointment with a Ford dealership on 2025-03-09. They will provide a full inspection report, if possible, I will upload here if I am allowed to update this report.

I have a 2018 Ford F-150 SuperCrew 4x4, with the current odometer at 61,500 miles. What component or system failed or system failed or malfunctioned, and is it available for inspection upon request? The 10R80 10-speed automatic transmission exhibits severe torque converter shudder/vibration. The torque converter and transmission fluid are original to the vehicle and are still installed. Yes, the vehicle and components are available for inspection upon request at any time. How was your safety or the safety of others put at risk? While driving at highway speeds (40–65 mph) under light throttle, the truck suddenly begins violent shuddering/vibrating that feels like driving over rumble strips. This causes the entire truck to shake, momentarily reduces engine power, and makes steering and braking feel unstable. The shudder is strong enough to blur the rear-view mirror and has occurred in heavy traffic and while towing, creating a serious risk of loss of vehicle control. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The shudder has been reproduced on multiple test drives by me and is identical to the symptoms described in Ford TSB 22-2219 and earlier TSBs for 2017–2020 F-150 10R80 torque converter shudder. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Not yet formally inspected by Ford for this specific failure, but the symptoms are identical to thousands of documented 10R80 cases that Ford has acknowledged via TSBs and goodwill repairs. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No check-engine light or transmission warning lamps. The shudder first appeared approximately May 2025 at around 54,000 miles and has steadily worsened. It now occurs on every drive between 20–25 and 40–55 mph.
